3D-Printed Guns: Your Questions Answered

Wouldn't Printed Guns Melt?

Almost certainly, and over time they eventually do. The issue isn't whether they eventually turn into a big blob of goo, but whether they deform enough to impede the working of the gun before it can be successfully fired a number of times. A milled piece of metal won't have this problem. A person called HaveBlue claimed to have fired a printed gun hundreds of times, however. NBC News noted that the buffer ring split after just six shots.
